Golden-winged Warbler

Golden-winged Warbler, another striking bird in the backyard on 10 May 2017. I have written about this fascinating species many times before in this blog. This species’ range has expanded into New England during the last century. Elsewhere, however, populations are declining, even disappearing. Several factors may be involved in the decline. Their secondary growth habitat is being replaced by more mature forests. As Blue-winged Warblers also enjoy a northward range expansion, they appear to out-compete and replace Golden-wings. Finally habitat destruction in Latin America probably contributes to the decline of the Golden-winged Warbler (Confer et al. 2011).
